What is Node-RED, and Why Use it with Cloud Firestore?
Node-RED is a popular, open-source IoT development platform that enables users to create complex workflows and integrations between various devices and services. By leveraging its visual interface and drag-and-drop functionality, developers can create powerful automation flows without extensive coding knowledge.
Cloud Firestore, on the other hand, is a NoSQL document database provided by Google Cloud Platform (GCP). It offers a scalable, secure, and real-time data storage solution, perfect for modern web and mobile applications.
Combining Node-RED with Cloud Firestore allows developers to create robust, real-time data processing pipelines, ideal for IoT, industrial automation, and other data-intensive applications.
The Node-RED Connection with Cloud Firestore: A High-Level Overview
To establish a connection between Node-RED and Cloud Firestore, you’ll need to:
- Create a Cloud Firestore database instance
- Generate a service account credential (JSON key file)
- Install the Node-RED Cloud Firestore node module
- Configure the Node-RED Cloud Firestore node with the service account credential
- Deploy and test your Node-RED flow
The Service Account Credential Conundrum: Understanding the “Error 5: Not Found” Issue
The most common issue when connecting Node-RED with Cloud Firestore is the “Error 5: Not Found” problem, which occurs when the service account credential is not properly configured or authenticated. This error can manifest in various ways, including:
- Incorrect service account credential format or syntax
- Invalid or expired service account credential
- Incorrectly configured Node-RED Cloud Firestore node
- Network connectivity issues or firewall restrictions
Troubleshooting the Service Account Credential Issue: A Step-by-Step Guide
Follow these steps to troubleshoot and resolve the service account credential issue:
Step 1: Verify Your Service Account Credential
Ensure your service account credential is valid and correctly formatted:
{ "type": "service_account", "project_id": "your-project-id", "private_key_id": "your-private-key-id", "private_key": "your-private-key", "client_email": "your-client-email", "client_id": "your-client-id", "auth_uri": "https://accounts.google.com/o/oauth2/auth", "token_uri": "https://oauth2.googleapis.com/token", "auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs", "client_x509_cert_url": "https://www.googleapis.com/robot/v1/metadata/x509/your-service-account-email" }
Double-check that:
- The JSON file is properly formatted and saved
- The service account email and project ID match your Cloud Firestore instance
Step 2: Configure the Node-RED Cloud Firestore Node
Verify that the Node-RED Cloud Firestore node is correctly configured:
[{"id":"node-red-cloud-firestore","type":"cloud-firestore","z":"your-flow-id","name":"","serviceAccount":"@iota.json","projectId":"your-project-id","collection":"your-collection-id","x":350,"y":200,"wires":[["node-red-debug"]]}]
Ensure that:
- The service account credential file is correctly referenced (e.g., “@iota.json”)
- The project ID, collection ID, and other node properties match your Cloud Firestore instance
Step 3: Check Node-RED Node Module Installation
Verify that the Node-RED Cloud Firestore node module is installed and up-to-date:
npm install node-red-contrib-cloud-firestore
Check that the module is listed in your Node-RED package.json file:
"dependencies": { "node-red-contrib-cloud-firestore": "^1.0.0" }
Step 4: Inspect Node-RED Flow Deployment and Logs
Deploy your Node-RED flow and inspect the deployment logs for any errors or warnings:
node-red-start
Check the Node-RED log output for any credential-related errors:
node-red-log
Step 5: Network Connectivity and Firewall Configuration
Verify that your network configuration and firewall rules allow communication between Node-RED and Cloud Firestore:
telnet firestore.googleapis.com 443
Ensure that your firewall and network settings permit outgoing connections to Cloud Firestore.
Conclusion: Resolving the Service Account Credential Issue
By following these steps, you should be able to troubleshoot and resolve the service account credential issue, successfully connecting your Node-RED project with Cloud Firestore. Remember to:
- Verify your service account credential format and syntax
- Configure the Node-RED Cloud Firestore node correctly
- Check Node-RED node module installation and deployment
- Inspect Node-RED flow deployment and logs for errors
- Ensure network connectivity and firewall configuration
With these troubleshooting steps, you’ll be well on your way to building robust, real-time data processing pipelines using Node-RED and Cloud Firestore.

Frequently Asked Question
Stuck with Node-RED connection issues with Cloud Firestore and service account credentials? We’ve got you covered! Check out these FAQs to troubleshoot and resolve the error 5 not found issue.
What is the error 5 not found issue in Node-RED?
The error 5 not found issue in Node-RED typically occurs when there’s a problem with the service account credentials or the Cloud Firestore connection. It means that Node-RED can’t find the required credentials or resources to establish a connection with Cloud Firestore.
How do I troubleshoot the service account credentials issue in Node-RED?
To troubleshoot the service account credentials issue, make sure you have created a service account in the Google Cloud Console and downloaded the JSON key file. Then, check if the JSON key file is properly configured in the Node-RED cloud Firestore node. Ensure that the file path is correct, and the credentials are not expired or revoked.
What is the correct way to configure the service account credentials in Node-RED?
To configure the service account credentials in Node-RED, go to the Cloud Firestore node and click on the three horizontal lines next to the “Service Account Key” field. Then, select “Import” and choose the JSON key file downloaded from the Google Cloud Console. Make sure to select the correct file and that it’s not corrupted.
Why does Node-RED throw an error 5 not found even with correct service account credentials?
Even with correct service account credentials, Node-RED might throw an error 5 not found if the Cloud Firestore node is not configured correctly or if there are network connectivity issues. Check if the Cloud Firestore node is properly configured, and the network connection is stable. Also, ensure that the Node-RED instance has the necessary permissions to access Cloud Firestore.
How can I resolve the Node-RED error 5 not found issue permanently?
To resolve the Node-RED error 5 not found issue permanently, ensure that you have followed the correct steps to configure the service account credentials and Cloud Firestore node. Regularly update your Node-RED instance and dependencies to avoid compatibility issues. Additionally, monitor your Node-RED logs to identify and fix any recurring issues.
